A To find the self-inductance we first need to know the magnetic field everywhere. From symmetry consideration the magnetic field inside the toroid must be circular ie along the azimuthal direction. The secondary current is in opposition to the source current.
Simply put inductance self-inductance is defined as the ability of an electric circuit to opposes changes to the current that is flowing through the system. The equation to determine inductance is e L didt. Thus the self-inductance is 22 0 LN B n I µπRl Φ 1126 We see that L depends only on the geometrical factors n R and l and is independent of the current I.
